Need help with part 2 of this stream

[alphaska]

Hi guys:
I wanna download this serious of lectures

http://videolectures.net/cikm08_elkan_llmacrf/

I can successfully download the part 1 of this lectures by using follow command.

rtmpdump -r rtmp://oxy.videolectures.net/video -y "flv:v000/41/ihy5uftwj2r7lhtln2cnkfykyz4prepu" -a video -s http://staticcdn.viidea.com/player/lib/flowplayer.nlimited-3.2.7.swf -w d8402fe25a901603234a67672a9962b33ac234a4d6d2049e9687d8cb49386723 -x 124837 -f "WIN 11,1,102,55" -p http://videolectures.net/mlss2011_candes_lowrank/ -o "Log-linear Models and Conditional Random Fields 1.flv" --resume

But when it comes to the part 2 of lecture, I can't get the rest of the part of videolectures. How can I get the correct flv address from web.
